 Yes , he was . I'm not imagining it.Finally , just when I got home , I turned around and looked at him.He was just standing there . He didn't smile . He just stood there . It was so obvious.What should I do ? I'm so scared . Can I call the police ? 
 Actually , I don't think you can call the police . Not yet at least.He hasn't done anything . And probably the police will just ignore it.But if anything happens again , then maybe you should call .
